The Acting Federal Opposition Leader has visited Tasmania's north-west, promoting the Coalition's plans to scrap the carbon and mining taxes.

Julie Bishop toured Haulmax at Wynyard, a company which builds trucks for the mining industry and is owned by businessman Dale Elphinstone.

Ms Bishop says the Coalition would work to grow the economy and create jobs in Tasmania if it wins the next federal election.

"Part of that will be to focus on the niche manufacturing, advanced manufacturing that is so successful here in Tasmania," she said.

"What we have to make sure is that government doesn't get in the way of the success of these businesses, that's why we will be repealing the carbon tax.

"I come from a state that has a growing and strong economy, we want to see that across the country and Tasmania in particular has the opportunity if it's freed from government regulation, free from the unnecessary burden of taxes and red tape will be able to grow."

Dale Elphinstone agrees the mining and carbon taxes should be abolished, saying they drive away investors.

"When people no longer feel comfortable to invest, and whether that's because of taxes or environmental issues or too much red tape, eventually they'll invest overseas, in Africa and places where they just don't have all of that issue, where there's a more welcoming environment for them," he said.

Mr Elphinstone's business Elphinstone Holdings is a major shareholder in Venture Minerals which has three proposed mines in the Tarkine.

He wants environmentalists from other states to stop campaigning against mining in the region, but says some areas are worth protecting.

"But you don't have to save half of Tasmania."

"We in Tasmania are not going to New South Wales and asking New South Wales to lock up half of their state and I'd ask people that live in Sydney or other places not to come and ask us to lock up our state where we can't have the resources we need to drive this part of the economy."
